The slippage tolerance might be not enough since the token is still new and has low liquidity.
Even though you've increased the slippage tolerance to 1.0% (the maximum one offered by the sites), but you can increase the slippage tolerance by yourself.
Check this site, they even suggest to increase it to 15% if it's still not working.
Gwei is related to Ethereum and ETH has high fees especially for their tokens so I suggest you reduce the withdrawal speed probably to standard in the image there just to lighten the output a bit by reducing the fees you would be paying.
That token run in BSC network, BSC source is almost same with ETH, that's why they also use "Gwei" name as their gas fee.
